She was found only wearing underwear and had no initial signs of trauma, Sgt. Dave Crivelli said Monday.

The Orange County Coroner’s Office conducted an autopsy Tuesday but the results were inconclusive and a cause of death was not determined, according to Sgt. Jose Quirarte.

“We’re investigating it right now as a suspicious death,” Quirarte said. “We were just able to identify her.”

Quirarte refused to discuss whether any injuries were discovered.

Detectives traveled to Lompoc Wednesday to try to determine how Posadas-Espinoza ended up in La Habra.

“There have been trips in the past to Southern California, but nothing pinpointed to La Habra,” Quirarte said.

Her car, a white 2013 Acura ILX sedan with the license plate 7EDU040, has not been located and police are asking for the public’s help. Anyone with information should call the La Habra police hot line at 562-383-4358 or Crime Stoppers Orange County at 1-800-TIP-OCCS.

Posadas-Espinoza is a licensed clinical social worker who first obtained her license in 1981, according to the California Medical Board.

Police suspect Posadas-Espinoza died days before her discovery. The man whose dog alerted on her body told police he’d walked by the area Friday and his dog went to the same spot, but that he did not investigate at the time.
